Hello,
I’m making a dashboard widget for the Lessonly developers badge. I’m trying to add a setting that lets the user select which column they want the widget to read from.
I’ve created a board with a locations column (EDIT: the pictured board is called Widget Test):
And I’ve added a columns field to the view settings, the configuration (don’t think its important but I’ll picture it just in case):
Yet, when I go to preview the settings display this:

Which I don’t understand, since the board has a locations column, and the view setting accepts Location as its column type. Anyway, if I click the Add Column → Add to Board, nothing happens, and my console displays this error message (similarly unsure if it is relevant):
I’d be grateful for any assistance, thanks.
